Poinsettia plant named &#39;fismars marble&#39;

ABSTRACT

A new Poinsettia plant particularly distinguished by medium to large size, bi-colored pink and cream bracts, with dark green foliage, ovate leaves with nearly no lobes, medium flowering response and a compact to medium size, round plant habit, is disclosed.

GENUS AND SPECIES

Euphorbia pulcherrima (Willd. Ex Klotzsch)

VARIETY DENOMINATION

‘Fismars Marble’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of poinsettia plant, botanically known as Euphorbia pulcherrima (Willd.) and hereinafter referred to by the cultivar name ‘Fismars Marble’. The new cultivar is the result of an induced mutation in the poinsettia plant ‘Fismars’ (U.S. Plant Pat. No. 14,977) made in the year 2003 in Ahrensburg, Germany.

In May 2003, young plants of ‘Fismars’ were irradiated in Ahrensburg, Germany. The treated plants were grown in Hillscheid, Germany, and were propagated by shoot tip cuttings. The resulting plants were screened for positive mutations and examined during the flowering period in winter 2004/2005. Among these plants, a pink-flowered plant was selected and asexually multiplied for further examination in 2005.

The new cultivar was created in 2003 in Ahrensburg, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Hillscheid, Germany over a two-year period. ‘Fismars Marble’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Europe on Feb. 9, 2005 and in Canada on Mar. 18, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Hillscheid, Germany.

-   -   1. Bi-colored bracts with a pink center and a cream colored         margin;     -   2. Medium to large size inflorescence;     -   3. Dark green foliage with ovate leaves that have nearly no         lobes;     -   4. Compact to medium size, rounded plant habit; and     -   5. A medium flowering response.

DESCRIPTION OF PHOTOGRAPHS

This new poinsettia plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a whole plant about 18-weeks old and in full flower, grown in a greenhouse in Hillscheid, Germany, in mid January of 2006.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Fismars Marble’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 18-week old plants which were planted as rooted cuttings in 14-cm pots on Jul. 28, 2005 and were pinched on Aug. 12, 2005, which left 7 to 8 leaves remaining. The plants were grown in a greenhouse at a minimum temperature of 18° C. and a ventilation temperature of 24° C. The plants initiated flowers under natural short-day conditions in fall. No black cloth was applied to the greenhouse to simulate short-day conditions. No growth regulator was applied. Color readings were taken under natural light in the greenhouse. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fismars Marble’ differs from the parental cultivar ‘Fismars’ (U.S. Plant Pat. No. 14,997) by having slightly convex, variegated pink bracts with cream margins instead of flat, red bracts. Additionally, ‘Fismars Marble’ develops few to no stamens while ‘Fismars’ has a normal number of stamens.

‘Fismars Marble’ differs from the commercial cultivar ‘Fiscor Marble’ (unpatented), by having deeper pink, shorter bracts as well as leaves with weaker lobes compared to ‘Fiscor Marble’. Additionally, ‘Fismars Marble’ develops few to no stamens while ‘Fiscor Marble’ develops a normal number of stamens under the same growing conditions

‘Fismars Marble’ differs from the commercial cultivar ‘490 Marble’ (U.S. Plant Pat. No. 8,833) by having shorter and smoother bracts compared to ‘490 Marble’ which has longer bracts that show distinct rugosity. Additionally, ‘Fismars Marble’ has a wider plant habit and a later flowering response compared to ‘490 Marble’.
